PlCKER-STICK CHECK.

SPECIFICATION forming part of Letters Patent N0. 752,342, dated February 16, 1904. Application filed October 24, 1903.. Serial No. 178,439. (No model.)

To all whom it may concern.-

Be it known that I, HENRY J. J ARRY, a citi zen of the United States,residing at Fall River, in the county of Bristol and State of Massachusetts, have invented new and useful Im: provements in Picker-Stick Checks, of which the following is a specification.

My invention relates to picker-stick checks for looms, the purpose of which is to check and hold the picker-stick and prevent the tendency of the shuttle to rebound and knock off the filling or weft, and has for its object to provide a device of this character which will be simple of construction, durable in use, com paratively inexpensive of production, and

which can be easily attached to looms now in general use.

, More particularly, one of the objects of my invention is to provide a device of this nature which will be readily capable of adjustment so that it will ofier more or less resistance to the picker-stick or, to use the technical terms of the art, which can be adjusted so that it will be short and sharp or long and easy.

With this and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation illustrating my improved check applied to the picker-stick of a loom. Fig. 2 is a bottom plan view thereof, the pickerstick being shown in section. Fig.3 is a section through the blade of the check and the adjustable stop on the line 3 3 of Fig. 1, the spring being omitted. Fig. 4: is a section through the pivotal axis of the blade on the line i iofFigl. 7

Referring to the drawings, 1 represents the lay-beam, and 2 the slot therein, in which the picker-stick 3 works. I

. 4 is a leather bufi'er against which the pickerstick strikes on its return after having delivered the shuttle.

5 is a plate secured to the under face of the beam 1 by screws 6 and having an offset portion 7 to which the blade 8 of the check is pivoted by the means now to be described.

Through a slot 9, formed in said offset portion 7 of the plate 5, (see Fig. 4,) is passed a bolt 10, having a nut 11 on its outer. end. Sleeved on this bolt is a bushing 12, having a reduced portion 13, on which the blade 8 is rotatably mounted. The opposite end 14 of the bushing 12 is octagonal or angular in shape, so that it may be held from turning when the nut l1 is tightened up. Adjacent to said angular portion 14 the bushing is provided with a flange portion 15 on one side and a larger flange portion 16 on the opposite side. Between these flange portions and the blade 8 are arranged several coils of a torsion-spring 17, one end of which is bent down and under to engage one of the recesses 18, formed in the end shoulders 19 of the flange portion 16, as shown in Figs. 1, 2, and 4. The other end of the spring 17 extends back of the blade 8 to a point slightly beyond the longitudinal center thereof, where it presses against the back of said blade. This end of the spring 17 is also arranged to approximately bear in the middle of the vertical width of said blade, as clearly shown in Fig. 1.

a By providing the two shoulders 19, having the recesses 18, the picker-check is rendered capable of being placed on the other side of the slot 2-of the lay-beam 1 by using a spring, blade, and plate 5 of opposite hand, in which case the bent end of the spring 17 would engage the other shoulder 19 from that shown in the drawings. In other words, the check is capable of use either on the right or on the left side of the picker-stick or on either end of thelay-beaml In this connection it may also be said that the means of attaching my improved picker-stick check will necessarily vary according to the type of loom in which it is employed, so that I do not in any way 0 restrict myself to the specific attaching means of a wrench applied to the angular portion 14 of said bushing the pressure exacted by the spring 17 on the blade 8 of the check may be increased or decreased, as will be obvious upon reference to Fig. 2 of the drawings.

The slot 9 in the offset portion 7 of the 10 and the parts carried thereby toward or away from the picker-stick slot 2, which adfered by the check to the picker-stick, as'wil'l be more fully described later. a

In order to further regulate the angle at which the blade 8 normally stands in the path of the stick, and consequently to aid, in connection with the adjustment just described, the resistance of the blade to" the stick, the

in Figs. 2 and 3) in the plate 5, whereby the block 23 and lug 22 can be adjusted toward or away from the picker-stick slot'2.

The front side of the blade'8, or that which engages the picker-stick, is slightly concaved, as shown in Fig. 2, whereby the resistanceto' the picker-stick is made to progressively increase, which result is also obtained by the progressive compression of the spring 17 as the blade 8 is forced backwardly by said stick.

It will now be seen thatby means of the" adjustment provided atthe pivotal axis of the blade of the check and of the'adjustment-of the stop-block 23 not only can the angle atence to the slot 2' be varied at will, but also that the blade can be bodilyadjusted laterally with respect to said slot withoutchanging the angle that it makes therewith. These features, taken in connection with the adjustability of the force with which the spring 17 presses upon the blade, enable the resistance offered by the check to thepicker-stick to be varied within wide limits, so that it may beset as short and sharp, or long and easy, or with any intermediate degree of resisting capacity.

Having thus described one'form in which my invention may be embodied, and without restricting myself to the preciseforms and dimensions shown, what I claim is 1. A picker-stick check for looms, comprising a check-blade pivotally supported adjacent to the picker-stick slot in the lay-beam, means to'adjust-the pivot of said bladetoward and justment aids in regulating the resistance of;
